460 Scania (Template:IPAc-en; prov. designation: Template:Mp or Template:Mp) is a background asteroid and a slow rotator from the central regions of the asteroid belt. It was discovered by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory on 22 October 1900.[1] The uncommon K-type asteroid has an exceptionally long rotation period of 164.1 hours and measures approximately Template:Convert in diameter. It was named after the Swedish region of Scania, where a meeting was held by the Astronomische Gesellschaft in 1904.[2]

Orbit and classification

Scania is a non-family asteroid from the main belt's background population.[3] It orbits the Sun in the central asteroid belt at a distance of 2.4–3.0 AU once every 4 years and 6 months (1,637 days; semi-major axis of 2.72 AU). Its orbit has an eccentricity of 0.11 and an inclination of 5° with respect to the ecliptic.[4] The body's observation arc begins at Vienna Observatory on 25 October 1900, three nights after its official discovery observation at Heidelberg.[1]

Naming

This minor planet was named after the Swedish region of Scania or Skåne by its Latin name, on the occasion of a meeting held in Lund by the Astronomische Gesellschaft in 1904 (AN, 166, 207Script error: No such module "Check for unknown parameters".). The Template:MoMP was also mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 50Script error: No such module "Check for unknown parameters".).[2]

Physical characteristics

In the Bus–Binzel SMASS classification, Scania is an uncommon K-type asteroid.[4]

Rotation period

In December 2017, a rotational lightcurve of Scania was obtained from photometric observations by Frederick Pilcher. Lightcurve analysis gave a well defined rotation period of Template:Val hours with a brightness variation of Template:Val magnitude (U=3Script error: No such module "Check for unknown parameters".). The results supersedes previous observations.[5][6]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Scania measures between 19.689 and 23.58 kilometers in diameter and its surface has an albedo between 0.189 and 0.262.[7][8][9] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1808 and a diameter of 21.63 kilometers based on an absolute magnitude of 10.8.[5]
